96 SLT780 Electrical Question
Swapping the CDI in my 96' SLT780 with a CDI from a 95' SLX780. Was not paying attention when I pulled it.The 96' SLX780 had a "Y" Harness that has a yellow lead that was hooked to the yellow wire going to the MFD. The other two connections were a green male and female bullet connector. I assume it goes inline with the green/red wire from the stator to CDI. I checked the polaris manual and the clymers manual, and dont see any evidence that it should be there. It is def a factory part.
-Any one seen this and able to verify that it gets hooked up like I did?
-Any clue why it is used?
-Can I just remove it and hook the yellow wire from the MFD to the yellow terminal on the board like all the other skis?
Another thing I noticed was that the 95' SLX780 had a harness that went in line with the green/red and had a connection that looked lke it was a capacitor that was then grounded. Wondering if I should be using that with the 95 CDI, but once again, no evidence of it in the diagrams.
Picture is of the Y harness from the 96' SLT780.
Picture is of the 95' SLX780 harness I did not use.

That capacitator looking thing was a fix for the service bulletin Polaris put out for an intermittent hard start on the 1995 SLX 780. PWC -95-13
I would keep it.
I am not sure about the "Y" wire?
Be careful using that SLX 780 CDI on your SLT 780. That SLX uses 28* of timing while the SLT came with 24*

Thanks for the reply. Never figured to look at the Service Bulletins....answered both questions. Thanks!
"Y" jumper was for erratic RPM reading on MFD. Tach signal sourced from exciter instead of charging coil.

That's the nitrous activation line. You need it in there...

I was thinking about it... Could be an easier installation than a one-off air to water intercooler.
Actually, I looked at it wrong that's the signal wire for the bottle warmer...
and you will install Nitrous on your SLH... You can be the guinea pig!

I've seen that post before. I don't think I'd have the guts to throw nitrous on an engine that sits right under me. I've seen plenty of bad nitrous fires or hoods blown off/apart from backfires just at the local 1/4 mile dragstrip. I still think it's awesome but not for me. I'll let Brad try it first...

Im not knocking down the only tree in my forest for a bit of speed....sorry! Its already bad enough that we have explosions happening almost 7k times a second only inches from our junk....
When are wg gonna go get some of your skis from "Storage". We need to start working on the SL's

So my goal is to get the drivetrain out of the parts Cougar this weekend and snag all the stuff I want/need for mine. I already have a ton of parts requests for stuff I was gonna let go with the car and have a couple guys that want to drive out to get parts from it. I think i'm going to try to get that out of the driveway in a couple weeks. I'll work from home one day and call the crusher to get the shell hauled off. Once that's out of the driveway I'll probably bring the pair of SL's back home and maybe the SLH so I have something to ride while we work on the SL's...
EDIT: I think Dan and I are gonna go check out that 00 SLH you pointed out this weekend at some point as well. Probably late Saturday or some time Sunday.
